T o all 'Lo/Lola t may concern c Be it known that I, ANDREW SHOOPMAN,

a citizen of thc United States, residing at Vera, in thecounty of Knoxand State of Texas7 have invented a new and useful Quick-AdjustablelVrench, of which the following is a specification. The presentinvention appertains to wrenches, and aims to provide, a quickadjustable wrench of novel and improved construction, which at the sametime is extremely simple and .inexpensive in construction, as well asbeing thoroughly practical and eflicient in use.

With the foregoing and other objects in view which will appear ask thedescription proceeds, the invention resides in the kcombination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes inthe preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without departing from the spirit of theinvention.

The inventidn is illustrated in the accompanying drawing, wherein Figure1 is a side elevation of the improved wrench.

Fig. 2 is a fragmental side elevation with the slide and dog shown insection.

Fig. 3 is a cross section taken on the line 3 3 of Fig. 1.

The wrench embodies a straight shank 1 formed from a bar orother'suitable stock, and having fastened upon its inner terminal asuitable handle 2, while a fixed or stationary jaw 3 is attached totheouter end of the shank. The shank is provided along one edge with aseries of ratchet teeth 4.

Slidably mounted upon the shank 1 is a slide 5 having the'openings 6 and7 at its outer Vand inner ends receiving the shank, and having thelongitudinal web 8 extending from end to end and bearing slidablyagainst that edge of the shank 1 opposite the teeth 4. The slide 5 isprovided at its outer end with an outstanding jaw 9 which is movablewith the slide toward and away from the jaw 3.

The slide 5'is provided adjacent to its inner end with anl opening 10extending transversely from one side to the other and exposing theratchet teeth 4, said opening 10 providing a loop 11 for receiving thethumb and nger of a hand for manipulating the slide 5. The slide 5 alsohas a recess 12 communicating at one end with the opening 10Specification of Letters Patent.

and'located betweentlie said openingl()` and the outer end orjaw 9 ofthe slide 5. The

recess 12 faces the ratchet teeth 4, and reccives one end of a dog orpawl 13, said end of the dog being pivoted upon a transverse pivot pin14 extending through the slide 5 and its recess 12. The dog 13 isprovided between its ends with ratchet teeth 15 engageable with theteeth 4, for preventing the movement of the slide 5 and jaw A9 away fromthe jaw 3, and the dog is provided at its free end with a finger piece16 projecting into the opening 10. The dog 13 is pressed toward theratchet teeth 4 by means of a coiled wire expansion spring 17 conlinedbetween theback of the dog and one wall of the recess 12, the dog andsaid wall of the recess being recessed, as at 18, for receiving the endsof the spring in order tohold it in place. The slide 5 is beveled orchamfered, as at 19, at the opposite sides of the shank 1 at that end ofthe opening 10 nearest the shank, whereby the thumb and finger can bereadily passed along the beveled ortions 19 into the opening 10 to graspthe nger piece 16 for moving it away from the shank in a convenient anddesirable manner.

In using the wrench, the slide 5 can be readily moved away from the jaw3 by moving the thumb and finger into the opening 10 from opposite sidesalong the beveled portlons 19, to grasp the finger piece 16, and

swing the dog away from the ratchet teeth 4, thus removing the teeth 15from the ratchet teeth 4, and it is then an easy matter to slide theslide 5 inwardly toward the han- Y dle. As soon as the finger piece 16isfreleased, the spring 17 will move the dog 13 into engagement with theteeth 4, and when the two jaws are brought to opposite sides of the nut,bolt or other object to be turned, the slide 5 can be easily slid towardthe jaw 3 for bringingk both jaws into engagement with the object, thedog 13 beingdragged over the teeth 4 and snapping into engagementtherewith', to prevent the inward movement of the slide 5 unless the dogis released manually. It is thus an easy matter to move the jaw 9 towardthe jaw 3 to accommodate the particular size of nut, bolt or otherobject. l

Having 'thus described the invention, what is claimed as new is: f
